1. A knockdown ring frame for a lamp shade, comprising:
- at least two rigid, elongated rods, each having opposite ends and formed to lie in a common plane and rigidly interconnect end-to-end to form a closed, planar ring, each said rod having a straight portion at each said end, each said portion having a transversely-extending tang formed thereon and spaced inwardly from a respective end; and
at least two connector sleeves, each having open, opposite ends and a straight segment at each said open end adapted to slidably receive an end of one of said rods coaxially therein, each said segment having a detent therein spaced inwardly from a respective end of said sleeve adapted to receive one of said tangs in locking, over-center engagement.

Abstract
A ring-shaped brace or frame for supporting the ribs of a knockdown-style lamp shade includes a plurality of rigid, elongated members which are formed to lie in a plane and interconnect end-to-end to form a rigid, closed polyagonal ring. Means are provided which receive ends of adjacent members and connect them in rigid, snap-together, pull-apart, locking engagement. Because the ring frame is quickly and easily assembled or disassembled by the consumer without the use of tools, it can be packed, along with the shade, in a compact, disassembled condition for shipment and sale.
